-Mainflux is modern, scalable, secure, open-source, and patent-free IoT cloud platform written in Go.
 
-It accepts user and thing (sensor, actuator, application) connections over various network protocols (i.e. HTTP,
-MQTT, WebSocket, CoAP), thus making a seamless bridge between them. It is used as the IoT middleware
-for building complex IoT solutions.
 
-For more details, check out the [official documentation][docs].
+## Introduction 📖
 
-Mainflux is member of the [Linux Foundation][lf] and an active contributor
-to the [EdgeX Foundry][edgex] project. It has been made with :heart: by [Mainflux Labs][company],
-which maintains the project and offers professional services around it.
+SuperMQ is a distributed, highly scalable, and secure open-source cloud platform for messaging and event-driven architecture (EDA). It is a planetarily distributed, highly scalable, and secure platform that serves as a robust foundation for building advanced real-time and reactive systems.
 
-## Features
+## Why SuperMQ Stands Out 🚀
 
-- Multi-protocol connectivity and bridging (HTTP, MQTT, WebSocket and CoAP)
-- Device management and provisioning (Zero Touch provisioning)
-- Mutual TLS Authentication (mTLS) using X.509 Certificates
-- Fine-grained access control (policies, ABAC/RBAC)
-- Message persistence (Cassandra, InfluxDB, MongoDB and PostgresSQL)
-- Platform logging and instrumentation support (Grafana, Prometheus and OpenTracing)
-- Event sourcing
-- Container-based deployment using [Docker][docker] and [Kubernetes][kubernetes]
-- [LoRaWAN][lora] network integration
-- [OPC UA](opcua) integration
-- Edge [Agent](agent) and [Export](export) services for remote IoT gateway management and edge computing
-- SDK
-- CLI
-- Small memory footprint and fast execution
-- Domain-driven design architecture, high-quality code and test coverage
+SuperMQ bridges the gap between various network protocols (HTTP, MQTT, WebSocket, CoAP, and more) to provide a seamless messaging experience. Whether you're working on IoT solutions, real-time data pipelines, or event-driven systems, SuperMQ has you covered. 🌐✨

-- [Docker](https://docs.docker.com/install/) (version 20.10)
-- [Docker compose](https://docs.docker.com/compose/install/) (version 1.28)
+## Installation 🛠️
 
-Developing Mainflux will also require:
-
-- [Go](https://golang.org/doc/install) (version 1.13.3)
-- [Protobuf](https://github.com/protocolbuffers/protobuf#protocol-compiler-installation) (version 3.6.1)
-
-## Install
-
-Once the prerequisites are installed, execute the following commands from the project's root:
+Clone the repository and start SuperMQ services:
 
 ```bash
-docker-compose -f docker/docker-compose.yml up
+git clone https://github.com/absmach/supermq.git
+cd supermq
+docker compose -f docker/docker-compose.yaml --env-file docker/.env up
 ```
 
-This will bring up the Mainflux docker services and interconnect them. This command can also be executed using the project's included Makefile:
+Or use the [Makefile](Makefile) for a simpler command:
 
 ```bash
 make run
 ```
 
-If you want to run services from specific release checkout code from github and make sure that
-`MF_RELEASE_TAG` in [.env](.env) is being set to match the release version
+For production deployments, check our [Kubernetes guide](https://docs.supermq.abstractmachines.fr/kubernetes). ⚙️
 
-```bash
-git checkout tags/<release_number> -b <release_number>
-# e.g. `git checkout tags/0.12.0 -b 0.12.0`
-```
+### Usage 📤📥
 
-Check that `.env` file contains:
-
-```bash
-MF_RELEASE_TAG=<release_number>
-```
-
->`docker-compose` should be used for development and testing deployments. For production we suggest using [Kubernetes](https://mainflux.readthedocs.io/en/latest/kubernetes/).
-
-## Usage
-
-The quickest way to start using Mainflux is via the CLI. The latest version can be downloaded from the [official releases page][rel].
-
-It can also be built and used from the project's root directory:
+#### Using the CLI:
 
 ```bash
 make cli
-./build/mainflux-cli version
+./build/supermq-cli status
 ```
 
-Additional details on using the CLI can be found in the [CLI documentation](https://mainflux.readthedocs.io/en/latest/cli/).
+This command retrieves the status of the SuperMQ server and outputs it to the console.
 
-## Documentation
+#### Using HTTP with Curl:
 
-Official documentation is hosted at [Mainflux Read The Docs page][docs]. Documentation is auto-generated, checkout the instructions on [official docs repository](https://github.com/mainflux/docs):
+```bash
+curl -X GET http://localhost:8080/status
+```
 
-If you spot an error or a need for corrections, please let us know - or even better: send us a PR.
+This request fetches the server status over HTTP and provides a JSON response.
 
-Additional practical information, news and tutorials can be found on the [Mainflux blog][blog].
+See our [CLI documentation](https://docs.supermq.abstractmachines.fr/cli) for more details.

 # Auth - Authentication and Authorization service

+Auth service provides authentication features as an API for managing authentication keys as well as administering groups of entities - `clients` and `users`.
+
+## Authentication
 
-# Authentication
 User service is using Auth service gRPC API to obtain login token or password reset token. Authentication key consists of the following fields:
+
 - ID - key ID
 - Type - one of the three types described below
-- IssuerID - an ID of the Mainflux User who issued the key
-- Subject - user email
+- IssuerID - an ID of the SuperMQ User who issued the key
+- Subject - user ID for which the key is issued
 - IssuedAt - the timestamp when the key is issued
 - ExpiresAt - the timestamp after which the key is invalid
 
-There are *three types of authentication keys*:
+There are four types of authentication keys:
 
-- User key - keys issued to the user upon login request
-- API key - keys issued upon the user request
+- Access key - keys issued to the user upon login request
+- Refresh key - keys used to generate new access keys
 - Recovery key - password recovery key
+- API key - keys issued upon the user request
+- Invitation key - keys used to invite new users
 
 Authentication keys are represented and distributed by the corresponding [JWT](jwt.io).
 
 User keys are issued when user logs in. Each user request (other than `registration` and `login`) contains user key that is used to authenticate the user.
 
-API keys are similar to the User keys. The main difference is that API keys have configurable expiration time. If no time is set, the key will never expire. For that reason, API keys are _the only key type that can be revoked_. This also means that, despite being used as a JWT, it requires a query to the database to validate the API key. The user with API key can perform all the same actions as the user with login key (can act on behalf of the user for Thing, Channel, or user profile management), *except issuing new API keys*.

 Recovery key is the password recovery key. It's short-lived token used for password recovery process.

-# Groups
-User and Things service are using Auth gRPC API to get the list of ids that are part of a group. Groups can be organized as tree structure.
-Group consists of the following fields:
+## Domains
 
-- ID - ULID id uniquely representing group
-- Name - name of the group, name of the group is unique at the same level of tree hierarchy for a given tree.
-- ParentID - id of the parent group
-- OwnerID - id of the user that created a group
-- Description - free form text, up to 1024 characters
-- Metadata - Arbitrary, object-encoded group's data
-- Path - tree path consisting of group ids
-- CreatedAt - timestamp at which the group is created
-- UpdatedAt - timestamp at which the group is updated
+Domains are used to group users and clients. Each domain has a unique route that is associated with the domain. Domains are used to group users and their entities.
+
+Domain consists of the following fields:
+
+- ID - UUID uniquely representing domain
+- Name - name of the domain
+- Tags - array of tags
+- Metadata - Arbitrary, object-encoded domain's data
+- Route - unique route of the domain used in messaging
+- CreatedAt - timestamp at which the domain is created
+- UpdatedAt - timestamp at which the domain is updated
+- UpdatedBy - user that updated the domain
+- CreatedBy - user that created the domain
+- Status - domain status

+## Personal Access Tokens (PATs)
+
+Personal Access Tokens (PATs) provide a secure way to authenticate with SuperMQ APIs without using your primary credentials. They are particularly useful for automation, CI/CD pipelines, and integrating with third-party services.
+
+### Overview
+
+PATs in SuperMQ are designed with the following features:
+
+- **Scoped Access**: Each token can be limited to specific operations on specific resources
+- **Expiration Control**: Set custom expiration times for tokens
+- **Revocable**: Tokens can be revoked at any time
+- **Auditable**: Track when tokens were last used
+- **Secure**: Tokens are stored as hashes, not in plaintext
+
+### Token Structure
+
+A PAT consists of three parts separated by underscores:
+
+```
+pat_<encoded-user-and-pat-id>_<random-string>
+```
+
+Where:
+
+- `pat` is a fixed prefix
+- `<encoded-user-and-pat-id>` is a base64-encoded combination of the user ID and PAT ID
+- `<random-string>` is a randomly generated string for additional security
+
+### PAT Operations
+
+SuperMQ supports the following operations for PATs:
+
+| Operation   | Description                          |
+| ----------- | ------------------------------------ |
+| `create`    | Create a new resource                |
+| `read`      | Read/view a resource                 |
+| `list`      | List resources                       |
+| `update`    | Update/modify a resource             |
+| `delete`    | Delete a resource                    |
+| `share`     | Share a resource with others         |
+| `unshare`   | Remove sharing permissions           |
+| `publish`   | Publish messages to a channel        |
+| `subscribe` | Subscribe to messages from a channel |
+
+### Entity Types
+
+PATs can be scoped to the following entity types:
+
+| Entity Type  | Description            |
+| ------------ | ---------------------- |
+| `groups`     | User groups            |
+| `channels`   | Communication channels |
+| `clients`    | Client applications    |
+| `domains`    | Organizational domains |
+| `users`      | User accounts          |
+| `dashboards` | Dashboard interfaces   |
+| `messages`   | Message content        |
+

+--header 'Content-Type: application/json' \
+--header 'Authorization: Bearer <access_token>' \
+--data '{
+    "duration": "720h"
+}'
+```
+
+### Using PATs for Authentication
+
+When making API requests, include the PAT in the Authorization header:
+
+```
+Authorization: Bearer pat_<encoded-user-and-pat-id>_<random-string>
+```
+
+#### Example: Creating a Client Using PAT
+
+```bash
+curl --location 'http://localhost:9006/c16c980a-9d4c-4793-8fb2-c81304cf1d9f/clients' \
+--header 'accept: application/json' \
+--header 'Content-Type: application/json' \
+--header 'Authorization: Bearer pat_etKoiXKTR6a0zdgsBHC00qJQAiaV3EKFh+Lmk+SgqXY=_u7@5fyjgti9V@#Bw^bS*SPmX3OnH=HTvKwmIbxIuyBjoI|6FASo9egjKD^u-M$b|2Dpt3CXZtv&4k+hmYYjk&C$57AV59P%-iDV0' \
+--data '{
+  "name": "test client",
+  "tags": [
+    "tag1",
+    "tag2"
+  ],
+  "metadata":{"units":"km"},
+  "status": "enabled"
+}'
+```
+
+This example shows how to create a client in a specific domain (`c16c980a-9d4c-4793-8fb2-c81304cf1d9f`) using a PAT for authentication. The PAT must have the appropriate scope (e.g., `clients` entity type with `create` operation) for this domain.
+
+### Wildcard Entity IDs
+
+When defining scopes for PATs, you can use the wildcard character `*` for the `entity_id` field to grant permissions for all entities of a specific type. This is particularly useful for automation tasks that need to operate on multiple resources.
+
+For example:
+
+- `"entity_id": "*"` - Grants permission for all entities of the specified type
+- `"entity_id": "specific-id"` - Grants permission only for the entity with the specified ID
+
+Using wildcards should be done carefully, as they grant broader permissions. Always follow the principle of least privilege by granting only the permissions necessary for the intended use case.
+
+### Scope Examples
+
+#### Allow Creating Any Client in a Domain
+
+```json
+{
+  "optional_domain_id": "domain_id",
+  "entity_type": "clients",
+  "operation": "create",
+  "entity_id": "*"
+}
+```
+
+This scope allows the PAT to create any client within the specified domain. The wildcard `*` for `entity_id` means the token can create any client, not just a specific one.
+
+#### Allow Publishing to a Specific Channel
+
+```json
+{
+  "optional_domain_id": "domain_id",
+  "entity_type": "channels",
+  "operation": "publish",
+  "entity_id": "channel_id"
+}
+```
+
+This scope restricts the PAT to only publish to a specific channel (`channel_id`) within the specified domain. No wildcard is used, so the permission is limited to just this one channel.
+
+#### Allow Reading All Dashboards
+
+```json
+{
+  "optional_domain_id": "domain_id",
+  "entity_type": "dashboards",
+  "operation": "read",
+  "entity_id": "*"
+}
+```
+
+This scope allows the PAT to read all dashboards within the specified domain. The wildcard `*` for `entity_id` means the token can read any dashboard in that domain.
+
+### Best Practices
+
+1. **Limit Scope**: Always use the principle of least privilege when creating PATs
+2. **Set Expirations**: Use reasonable expiration times for tokens
+3. **Rotate Regularly**: Reset token secrets periodically
+4. **Audit Usage**: Monitor when tokens are used
+5. **Revoke Unused**: Remove tokens that are no longer needed
+
+### Implementation Details
+
+PATs are stored in the database with the following schema:
+
+```sql
+CREATE TABLE IF NOT EXISTS pats (
+    id              VARCHAR(36) PRIMARY KEY,
+    name            VARCHAR(254) NOT NULL,
+    user_id         VARCHAR(36),
+    description     TEXT,
+    secret          TEXT,
+    issued_at       TIMESTAMPTZ,
+    expires_at      TIMESTAMPTZ,
+    updated_at      TIMESTAMPTZ,
+    revoked         BOOLEAN,
+    revoked_at      TIMESTAMPTZ,
+    last_used_at    TIMESTAMPTZ,
+    UNIQUE          (id, name, secret)
+)
+
+CREATE TABLE IF NOT EXISTS pat_scopes (
+    id                  VARCHAR(36) PRIMARY KEY,
+    pat_id              VARCHAR(36) REFERENCES pats(id) ON DELETE CASCADE,
+    optional_domain_id  VARCHAR(36),
+    entity_type         VARCHAR(50) NOT NULL,
+    operation           VARCHAR(50) NOT NULL,
+    entity_id           VARCHAR(50) NOT NULL,
+    UNIQUE (pat_id, optional_domain_id, entity_type, operation, entity_id)
+)
+```
+
+### Authorization
+
+When a PAT is used for authentication:
+
+1. The system parses the token to extract the user ID and PAT ID
+2. It verifies the token hasn't been revoked or expired
+3. It checks if the requested operation is allowed by the token's scopes
+4. If all checks pass, the operation is authorized
